2. You are an anti-tank soldier 400 meters atop a cliff, and while scanning the canyon below, you spot a well camouflaged enemy tank. The crew is using the tank for cover as they fill their canteens with water at an oasis. At a quick glance of your map, the oasis appears to be 300 meters from the base of the mountain on which you stand. At what angle must you fire your RPG-29 in order to destroy the tank?
